Disabling the Outputs

The outputs of the power supply can be disabled or enabled from the front panel using
the key.
Output On/Off
• When the power supply is in the "Off" state, the OFF annunciator turns on and the
three outputs are disabled. The OFF annunciator turns off when the power supply
returns to the "On" state. When the outputs are disabled, the voltage value is 0 volts
and the current value is 0.05 amps.
• The output state is stored in volatile memory; the output is always disabled when
power has been off or after a remote interface reset.
While the outputs are disabled, the control knob and resolution selection keys are
still working. If the display is in the meter mode, you cannot see the changes of
output voltage and current settings on the display when turning the knob. To see
or check the changes when the outputs are disabled, the display should be in the
limit mode.
• Front-panel operation:
You can disable the outputs by pressing the
between the output Off and On states.
• Remote interface operation:
OUTPut {ON|OFF}
The outputs are disabled when the "OFF" parameter is selected and enabled when the
"ON" is selected.

Knob Locking

The knob locking function can be used to disable the knob, thereby preventing any
unwanted changes during an experiment, or when you leave the power supply
unattended.
To disable the knob, press the resolution selection key until the blinking digit
disappears.
